Which of the following will be the number of chromosomes in the sperm of a Sahiwal bull?

Answer: Option A

The number of chromosomes in the sperm of a Sahiwal bull is 30.
The Sahiwal originated in the dry Punjab region which lies along central Punjab. Sahiwal bulls have demonstrated the ability to sire small, fast-growing calves, noted for their hardiness under unfavourable climatic conditions.
A bull's sperm has 30 chromosomes, including one which is either an X- or a Y-chromosome whose genes code for sex.
